The Cancer Alliance Data, Evidence and Analysis Service (CADEAS)

Our purpose and work programmes

CADEAS was established during 2017/18 and supports Cancer Alliances’ analytical needs enabling them to lead transformation using a whole pathway and cross-organisational approach.

Funded by the National Cancer Programme, CADEAS is a partnership between NHS England and Public Health England. The partnership enables the work programme to be strategically focused in line with the National Cancer Programme’s priorities and aligned with approaches and methodology of the National Cancer Registration and Analysis Service (NCRAS) in Public Health England. It also allows access to a broad range of cancer data and analytical expertise.

CADEAS’ purpose is to help ensure Cancer Alliances:

• take a data-driven approach to support meeting and sustaining operational performance; and transforming cancer outcomes across their local cancer system;

• track the implementation of national transformation priorities and evaluate their impact to share evidence and spread best practice; and

• have access to the very latest analysis to support delivery of transformation activities.


Our work programmes for 2020/21, 2019/20 and 2018/19 were developed in consultation with Cancer Alliances, the National Cancer Programme and the National Cancer Registration and Analysis Service in Public Health England. 

Our core offer to Cancer Alliances is to:

• give Cancer Alliances access to timely and consistent data held nationally on operational performance and cancer activities, outputs and outcomes in their area to track progress and to identify areas for action;

• provide products such as tools, models and analysis of variation using a variety of analytical techniques to give greater depth and insights into key priority areas;

• offer advice and guidance to support Cancer Alliances to establish effective local evalautions; and

• synthesise emerging evidence generated across Cancer Alliances and publish and disseminate national findings so that all Cancer Alliances can learn from what works.

We would like to thank patients and clinicians who provide the information that is collected by the NHS as part of patients' cancer care.

Cancer Alliance date signposting guide

CADEAS have produced a data signposting guide, targeted at Cancer Alliances This synopsis aims to outline where cancer data and information can be found for sub-national geographies in England. It is structured using key topics in the 2015 Cancer Taskforce report ‘Achieving World Class Cancer Outcomes: Strategy for England 2015 - 2020’. 

CADEAS Signposting Guide for Cancer Alliances

This is a summary of the document Cancer statistics: availability and location updated by the Cancer Alliance Data Evidence and Analysis Service (CADEAS) in September 2018.


Cancer Alliance, STP and CCG summary grid of key indicators

CADEAS publish summary indicator grids each month, containing cancer metrics by Cancer Alliance, Sustainability and Transformation Partnership (STP) and Clinical Commissioning Group (CCG).  By colour coding values based on comparisons with the national benchmark, expected values or operational standards, Alliances and their key stakeholders can identify areas of success and potential areas for improvement. Data in the grids should be considered alongside other sources of information for contextual and richer interpretation.

CADEAS Cancer Alliance data packs by CCG

The CADEAS data packs aim to provide all Cancer Alliances in England with a snapshot of cancer in their local populations, with a breakdown by CCG.  Each pack highlights variation in each Alliance footprint and helps to identify priority areas for action.

COVID-19 Cancer Equity Data Pack: Urgent referral and first treatment activity

The Cancer Alliance Data, Evaluation and Analysis Service (CADEAS), part of the NHS Cancer Programme, and National Cancer Registration and Analysis Service (NCRAS), have produced two equity data packs. These present the latest national and regional activity data on both the number of:

  • Urgent suspected Two-Week Wait referrals, and
  • First definitive treatments

The data is further broken down by tumour type and patient factors: deprivation, age, sex and ethnicity. The figures present the working day adjusted proportion compared to pre-pandemic levels. A national summary of the data is included in each pack.

These data are being used to directly inform activity in the restoration and recovery of cancer services, including targeted messaging in the national Help Us Help You (HUHY) campaign to support people coming forward with symptoms indicative of cancer to their GP. The data and findings are also being shared with Cancer Alliances and regional teams to support the targeting of local campaign messages. These data will be monitored, updated and published monthly.

Median pathway analysis by patient demographics, cancer stage and route to diagnosis, for colorectal, lung and prostate cancer (2013-2017)

CADEAS have produced reports on the analysis of median pathway length for patients diagnosed with colorectal, lung and prostate cancers (2013-2017). The reports aim to further Cancer Alliances’ understanding of variation in median days taken for different segments of the patient pathway from referral to first treatment, by socio-demographic factors, cancer stage, routes to diagnosis and geography, and to help enable Cancer Alliances to:

      • investigate whether the variations are justified;
      • discuss implementation of local strategies to reduce variation and address health inequalities; and
      • identify and share best practice for faster diagnosis and improving patient experience.

Analysis of 62-day pathways using 2017-2018 Cancer Waiting Times data for colorectal, lung and prostate cancers

CADEAS have produced reports which aim to provide Cancer Alliances with analysis of pathways with a 62-day Cancer Waiting Times (CWT) record for colorectal, lung and prostate cancers. This will enable Cancer Alliances to support:

• implementation of the best practice times pathways; and

• meeting 62-day CWT operational standards.

The work is also aimed at helping Cancer Alliances understand where variations are occurring across Alliances, as well as understanding pathway variation between cancer types.

This National Report has been segmented by Cancer Alliance.

Evidence and Evaluation

Cancer Alliance local evaluation resources 2019/20

As set out in the 2019/20 NHS Planning Guidance, all Cancer Alliances will be required to undertake local evaluations in prescribed areas, specifically;

      • approaches to increase screening uptake
      • each additional project where the intervention is novel, and the evidence is less established e.g. personalised (stratified) follow up care beyond breast, colorectal, and prostate pathways

Evaluation is crucial for developing evidence and best practice that can be shared across all Cancer Alliances and with the National Cancer Programme to support evidence-based decision making, thus occupying a central role in the policy cycle. 

To support Cancer Alliances in carrying out local evaluations in the prescribed areas, as reflected above, CADEAS has developed a suite of evaluation resources. The resources listed below are designed to serve as a guide and support Cancer Alliances throughout the evaluation process.

      1. Evaluation how to guide: practical steps to undertaking evaluation
      2. Evaluation framework: evaluation questions, data collection methods and sources
      3. Introduction to approaches to evaluation and data collection reference guide
      4. Blank logic model and evaluation templates
      5. Commissioning an evaluation reference guide

These resources are intended to complement each other and should be read together to guide the establishment and delivery of local evaluation.
